Despite their imposing presence, quantum computers are delicate beasts, and their errors are among the main bottlenecks that the quantum computing community is actively working to address. Failing this, promising applications in finance, drug discovery, and materials science may never become real. That’s the reason why Google touted the error-correction capacities of its latest quantum computing chip, Willow. And IBM is both working on delivering its own “fault-tolerant” quantum computer by 2029...
